Apparently there are thousands of trucks ( https://www.lifesitenews.com/news/canada-truckers-freedom-convoy-ottawa/ ). Let's say for arguments sakes that it's 3,000 (happy to have a better figure from someone) If each truck, including spacing, occupies 50 metres, that 150 kms. Wouldn't take many more trucks to bring that to 150 miles. Even at just 2,000 trucks at 40 metre spacing, that's still 80 km - quite an impact.
